The success of the capacitive sensor scroll wheel used in devices such as the iPod has caused other consumer product development teams to evaluate capacitive sensors to enhance the user interface and ...

When you look at switching solutions for electronic wearables, your options are limited. With a clever application of conductive fabric and thread, you can cobble together a simple switch, but the ...

You can’t have a touch sensitive switch without a way to detect the presence of a finger! A touch sensor, especially a capacitive touch sensor, has some surprisingly sophisticated electronics to ...

This PLL-based circuit implements a touch-switch circuit using the PC board or small metal pads as sensors; it is radiometric and thus insensitive to changes in temperature and supply voltage.

The new CA18CB..IO and CA30CB..IO capacitive sensors with IO-Link communication offer exceptional sensing performance and simplified adjustments through their integrated LED bar, which displays on/off ...

Today’s homes and workplaces are increasingly pervaded by smart appliances, which are designed to be attractive and reliable, and ideally should support interactions that are as easy and rewarding as ...

Apple is examining a shift from a force sensor in AirPods to a capacitive touch system to make a set easier to control, and provide new options. The latest in Apple's surprisingly long history of ...

• Trapped acoustic resonance is most simply described with an analogy: the ringing of a bell. • Microprocessors control the frequency of the mechanical resonance and monitors its decay. • A thicker ...

Capacitive touch sensors are entirely in the domain of DIY, requiring little more than a carefully-chosen conductive surface and a microcontroller. This led [John Phillips] to ask why not embed such ...
